I noticed some drone with mine as well. Not a lot, but some. I didn't find it as offensive as @
AJ, but it is there. I was a little surprised at this from an optional OEM endorsed Exhaust. What I did find offensive is the puny size of the front half of the mid-pipe. I had a 2.5" mid pipe made up with an 18" core Magnaflow Resonator. That made the tone a little deeper, got rid of some tininess, and pretty much killed the drone.
Everyone's ear and tolerance is a little different...
